3,4-Methylenedioxymethamphetamine (also known as ecstasy, E, XTC, emma, molly, mandy, pingers, and MDMA) is a classical entactogen substance of the amphetamine class. It is the most well-known and widely-used member of the entactogens, a diverse group that includes MDA, methylone, 4-MMC, and 6-APB. It produces its effects by promoting the release of serotonin, dopamine, and norepinephrine in the brain, particularly serotonin.

MDMA was first developed in 1912 by the pharmaceutical company Merck.[1] However, human use was not reported until the 1970s, when it became known to underground psychotherapy circles in the United States.[2] In the early 1980s, it spread into nightlife and rave culture, which eventually resulted in federal scheduling in 1985.[3] By 2014, it was estimated to be one of the most popular recreational drugs in the world, alongside cocaine and cannabis.[4]

Today, recreational MDMA use is widely associated with dance parties, electronic dance music, and the clubbing and raving scenes.[5] Researchers are currently investigating whether MDMA may assist in treatment-resistant post-traumatic stress disorder (PTSD), social anxiety in autistic adults,[6] and anxiety in those with life-threatening illness.[7][8][9]

Subjective effects include stimulation, anxiety suppression, disinhibition, enhanced empathy and sociability, relaxation, and euphoria. It is classified as an entactogen due to how it facilitates feelings of closeness with one's self and others. A notable property of MDMA is that tolerance builds unusually quickly and many users report that it dramatically loses effectiveness if used on a frequent basis.

It is usually recommended to wait for one to three months between each use to give the brain adequate time to restore serotonin levels and avoid toxicity. Additionally, using excessively high doses and multiple redosing is highly discouraged as this is thought to significantly increase the toxicity of MDMA.

MDMA has moderate to high abuse potential but a conversely low potential for a genuine psychological dependence or addiction which appears even lower than cannabis (lower than 10%). Interestingly, MDMA’s potential for overuse and dependence or addiction can actually be greatly influenced by certain geographical components such as in other cultures or subcultures similarly to ketamine. Although ketamine‘s addiction potential is still notably higher across various cultures then compared to MDMA. Acute adverse effects of MDMA are usually the result of high amounts or multiple doses; either when done too frequently or excessively within a 24 hour period. Although single dose toxicity can still occur in susceptible individuals.[10] The most serious short-term physical health risks of MDMA are overheating and dehydration, which has resulted in deaths.[11] It has also been shown to be neurotoxic at high doses;[12] however, it is unclear how much this risk applies to typical recreational usage.[13] MDMA may cause excessive thirst, and inability to urinate the water, which may cause water intoxication and electrolyte imbalance. MDMA has been shown to cause sexual dysfunction, including erectile dysfunction and delayed orgasm (see subjective effects).

It is highly advised to use harm reduction practices if using this substance.

History and culture

Patent Certificate for Merck's synthesis of MDMA, dated 1912

MDMA was first synthesized in 1912 by the German chemist Dr. Anton Köllisch while employed at the pharmaceutical company Merck. Köllisch was in the process of developing agents that would help manage excess bleeding and was interested in MDMA synthesis because it was an intermediate in the production of methylhydrastinin, the methylated analog of the hemostatic agent hydrastinine. There are no indications of interest in MDMA as an active agent itself.[1]

It was not mentioned again until 1927, when Dr. Max Oberlin conducted the first proven pharmacological tests at Merck while searching for compounds with a similar action spectrum to adrenaline or ephetonine. Despite promising results, research was halted due to rising substance prices.[1]

In 1965, the American chemist Alexander Shulgin synthesized MDMA as an academic exercise but did not test it for psychoactivity.[14][2] Shulgin claims to have first heard about the effects of MDMA in 1967 from a student and decided to experiment with it himself. He was impressed with the effects of the substance and believed it could have therapeutic utility. He advertised it to therapists and psychiatrists which led it to gain some popularity as an adjunct treatment for various psychological disorders.[2]

During this period, psychotherapist Dr. Leo Zeff came out of retirement and subsequently introduced the then-legal MDMA to over 4,000 patients. From the mid-1970s to the mid-1980s there was a growth of clinicians using MDMA (then known as "Adam") in California.[15]

Recreational use of MDMA became popular at around the same time, particularly in nightclubs, eventually catching the attention of the Drug Enforcement Administration (DEA). After several hearings, a US Federal Administrative Law Judge recommended that MDMA should be made a Schedule III controlled substance so that it could be used in the medical field. Despite this, the director of the DEA overruled this recommendation and classified MDMA as a Schedule I controlled substance.[16][14]

In the United Kingdom, the 1971 Misuse of Drugs Act, which had already been altered in 1977 to include all ring-substituted amphetamines like MDMA, was further amended in 1985 to refer specifically to Ecstasy, placing it in the Class A category.[15]

Chemistry

MDMA, or 3,4-methylenedioxy-N-methylamphetamine, is a synthetic molecule of the substituted amphetamine class. Molecules of the amphetamine class all contain a phenethylamine core comprised of a phenyl ring bound to an amino (NH2) group through an ethyl chain, with an additional methyl substitution at Rα. In addition to this, MDMA contains a methyl substitution on RN, a feature it shares with methamphetamine. Critically, the MDMA molecule also contains substitutions at R3 and R4 of the phenyl ring with oxygen groups -- these oxygen groups are incorporated into a methylenedioxy ring through a methylene bridge. MDMA shares this methylenedioxy ring with other entactogens and stimulants like MDA, MDEA and MDAI.

Pharmacology

MDMA acts primarily as a releasing agent of the three principal monoamine neurotransmitters serotonin, norepinephrine, and dopamine through its action at trace amine-associated receptor 1 (TAAR1) and vesicular monoamine transporter 2 (VMAT2).[17][18][19] MDMA is a monoamine transporter substrate (i.e. a substrate for the transporters for dopamine (DAT), norepinephrine (NET), and serotonin (SERT)), enabling it to enter monoaminergic neurons via these neuronal membrane transport proteins.[18] By acting as a monoamine transporter substrate, MDMA produces competitive reuptake inhibition at the neuronal membrane transporters, competing for endogenous monoamines for reuptake.[18][20]

MDMA inhibits both vesicular monoamine transporters (VMATs), the second of which (VMAT2) is highly expressed within monoamine neurons vesicular membranes.[19] Once inside a monoamine neuron, MDMA acts as a VMAT2 inhibitor and a TAAR1 agonist.[18][21] The inhibition of VMAT2 by MDMA results in increased concentrations of the aforementioned monoamine neurotransmitters in the cytosol of the neuron.[19][22] Activation of TAAR1 by MDMA triggers protein kinase signaling events which then phosphorylates the associated monoamine transporters of the neuron.[18]

Subsequently, these phosphorylated monoamine transporters either reverse transport direction – i.e. move neurotransmitters from inside the cell to the synaptic cleft – or withdraw into the neuron, respectively producing the inflow of neurotransmitters and noncompetitive reuptake inhibition at the neuronal membrane transporters.[18] MDMA has ten times more affinity for uptake at serotonin transporters compared to dopamine and norepinephrine transporters and consequently has mainly serotonergic effects.[23]

MDMA also has weak agonist activity at postsynaptic serotonin receptors 5-HT1 and 5-HT2 receptors, and its more efficacious metabolite MDA likely augments this action.[24][25][26][27] Cortisol, prolactin, and oxytocin quantities in serum are increased by MDMA.[28]

Additionally, MDMA is a ligand at both sigma receptor subtypes, though its efficacies at these receptors and the role that they play have yet to be elucidated.[29]

Subjective effects

Disclaimer: The effects listed below cite the Subjective Effect Index (SEI), an open research literature based on anecdotal user reports and the personal analyses of PsychonautWiki contributors. As a result, they should be viewed with a healthy degree of skepticism.

It is also worth noting that these effects will not necessarily occur in a predictable or reliable manner, although higher doses are more liable to induce the full spectrum of effects. Likewise, adverse effects become increasingly likely with higher doses and may include addiction, severe injury, or death ☠.

Dose-effects relationship from analyzed samples

The optimal single oral dose for an average user may be around 90 mg going by this diagram. Note that the percentages at the bottom are too outdated to guide in estimating substance content in current pills: The average concentration of MDMA in ecstasy pills, tested in a drug checking program in Zurich, doubled between 2010 and 2018. The percentage of pills containing more than 120 mg MDMA rose from 4% to 73%. In the same period, the rate of pills containing other psychoactive compounds dropped from 53% to 7%.[44]

Names and forms

Names

MDMA pills, commonly called Ecstasy
Off-white MDMA crystals, commonly called Molly

Since the 1980s, MDMA has become widely known as "Ecstasy" (shortened to "E", "X", or "XTC"), usually referring to its street forms as illicitly pressed pills or tablets.[46] The American term "Molly" and the British equivalent term "Mandy" originally referred to crystal or powder MDMA that was purported to be of high purity and free of adulteration.[47] However, it has since evolved into a generic street term for any number of euphoric stimulants that are sold in powder or crystal form.[citation needed]

Forms

MDMA can be found in the following forms:

Crystals

Crystals or powder (commonly called Molly) is a white to brownish substance which can be dissolved, crushed, put into gel capsules or edible paper ("parachutes"). It can be administered orally, sublingually, buccally or via insufflation ("snorting" or "sniffing").

Pills

Skull and crossbones darktextred2.png

Do not trust underground brand names, they are easily falsified

The previously good reputation of 'Mistubishi's' amongst ecstasy-users has been dealt a blow with the discovery of deadly batches (PMA has been found in White Mitsubishi,[48] PMMA has been found in Red Mitsubishi[49])

Pills are the most common form in which MDMA is sold, and are commonly referred to as Ecstasy. They often contain other substances or adulterants that range from anything from MDA, MDEA, amphetamine, methamphetamine, caffeine, 2C-B or mCPP to synthesis by-products such as MDP2P, MDDM or 2C-H. They can also contain an array random substances such as research chemicals, prescription drugs, over-the-counter drugs, poisons or nothing at all. It is strongly recommended to take harm reduction measures such as using a reagent testing kit when ingesting unknown pills.

Dosages

Common dosages for MDMA-assisted therapy:

  • 1.1-1.7 mg/kg, or 80-120 mg for a 70 kg person.
  • Kilo body weight + 50 in milligrams

MDMA-assisted psychotherapy for PTSD

In 2011, a pilot study on 20 patients demonstrated promising results in the treatment of post-traumatic stress disorder (PTSD). After two or three MDMA-assisted psychotherapy sessions, 83% of the patients no longer met the criteria for PTSD, compared to only 25% in the control group where MDMA was replaced with a placebo. The results sustained at two and twelve months after the treatment. The MDMA and placebo group both received non-drug psychotherapy before and after the sessions. In the study, a dose of 125mg MDMA plus a 62.5mg supplemental dose after 2 hours have been administered.[51] After completion of the study, the patients from the placebo group also received MDMA-assisted psychotherapy, and a long-term follow-up study of 19 patients published in 2013 shows that even after three years the positive results maintained.[51]

In 2017, the FDA granted MDMA a breakthrough therapy designation for PTSD, meaning if studies show promise, a review for potential medical use could occur more quickly.[52] Phase 3 clinical trials to look at effectiveness and safety have already begun, and are expected to be completed in 2021, meaning the FDA could approve treatment as early as 2022.[53] [54]

R-MDMA

MDMA is typically produced and consumed in its racemic form (known as SR-MDMA) which consists of equal parts S-MDMA and R-MDMA. A 2017 study found that high doses of R-MDMA administered in mice increased prosocial behavior and facilitated fear-extinction learning but did not produce hyperthermia or signs of neurotoxicity. This is thought to owe itself to the lower dopamine release R-MDMA displays relative to SR-MDMA. This result suggests that R-MDMA may be a safer and more viable therapeutic than racemic MDMA.[55] However, more research is needed to validate this finding.

Toxicity and harm potential

Table from the 2010 ISCD study ranking various drugs (legal and illegal) based on statements by drug-harm experts. MDMA ("Ecstacy") was found to be the 16th overall most dangerous drug.[56]
Radar plot showing relative physical harm, social harm, and dependence of MDMA[57]

The short-term physical health risks of MDMA consumption include dehydration, bruxism, insomnia, hyperthermia,[58][59] and hyponatremia.[60] MDMA generally does not cause any serious or life threatening effects by itself unless it is associated with other extraneous factors such as exposure to prolonged high ambient temperature and humidity, prolonged physical activities, poor intake of water and lack of acclimatization.[61]

Continuous activity without sufficient rest or rehydration may cause the user's body temperature to rise to dangerous levels, and loss of fluid via excessive sweating puts the body at further risk as the stimulating and euphoric qualities of MDMA may cause the user to become oblivious to their physical condition.

Diuretics such as alcohol may exacerbate these risks further due to causing excessive amounts of dehydration. Users are advised to pay close attention to their water intake, drinking neither too much nor too little, and to take care not to overexert themselves to avoid heat-stroke, which can be fatal.

Toxic dose

The exact toxic dosage is unknown, but considered to be far greater than its effective dose.[citation needed]

Water intoxication and electrolyte imbalance

Water intoxication symptoms typically show up when a person consumes more than about 3-4 liters of water within an hour.[62][63] Also, an important cause of death following MDMA use is hyponatremia, low blood sodium levels as a result of drinking too much water.

Ecstasy users have reported that xerostomia (dry mouth) is common.[64][65] The excessive drinking observed in case reports of MDMA use may be caused by hyperpyrexia, a change in the primary drive to drink, and exposure to harm reduction messages that emphasize the need to drink water.[66] Higher doses of MDMA result in an overall difficulty when it comes to urination.[67] Urinary retention is caused by MDMA’s promotion of the release of anti-diuretic hormone (ADH); ADH is responsible for regulating urination. This effect can be lessened by relaxing, but can also be relieved by placing a hot flannel over the genitals to encourage blood flow.[68][69] However, MDMA causes water retention and dilution of electrolytes. Consequently, overhydration has caused death from water intoxication.[70] It was a main cause of the Death of Leah Betts who consumed an excstasy tablet followed by approximately 7 litres (1.8 US gal) of water in a 90 minute period, that resulted in water intoxication and hyponatremia, which in turn led to serious swelling of the brain, irreparably damaging it.

Users may experience signs of dehydration such as dry mouth and sweating while dancing or in a hot environment.

Water intoxication and electrolyte imbalance prevention

It is advised that users have hydration available, drink to thirst and never over-drink.[citation needed]

  • Avoid consuming more than 3 liters of water within a few hours.
  • Hyponatremia is preventable by drinking fluid containing sodium, such as that contained in sports drinks (typically ~20mM NaCl).

Neurotoxicity

The neurotoxicity of MDMA use is the subject of considerable debate. Scientific study has resulted in the general agreement that, although it is physically safe to try in a responsible context, the administration of repeated or high dosages of MDMA is most certainly neurotoxic in some form.

Administration of MDMA causes subsequent down-regulation of serotonin reuptake transporters in the brain. The rate at which the brain recovers from serotonergic changes is unclear. One study demonstrated lasting serotonergic changes in some animals exposed to MDMA.[71] Other studies have suggested that the brain may recover from serotonergic damage.[72][73][74]

It is thought that MDMA's metabolites play a large role in the uncertain levels of neurotoxicity. For example, a metabolite of MDMA called alpha-Methyldopamine (α-Me-DA, which is known to be toxic to dopamine neurons[75][18]) was thought believed to be involved in the toxicity of MDMA to serotonin receptors.

However, one study found this to not be the case as direct administration of α-Me-DA did not cause neurotoxicity.[18] Additionally, MDMA injected directly into the brain was found to not be toxic, implying a metabolite is responsible for the toxicity when MDMA is administered via insufflation or oral consumption.[18]

This study found that although α-Me-DA is involved, it is a further metabolite of α-Me-DA involving glutathione that is primarily responsible for the selective damage to 5-HT receptors triggered by MDMA/MDA.[18]This metabolite forms in higher concentrations when core temperature is elevated. It is taken up into serotonin receptors by its transporters and metabolized by MAO-B into a reactive oxygen species which can cause neurological damage.[18][76]

Retracted article on dopaminergic neurotoxicity of MDMA

Severe dopaminergic neurotoxicity in primates after a common recreational dose regimen of MDMA[77] is an article by George A. Ricaurte which was published in September 2002 in the peer-reviewed journal Science, one of the world's top academic journals. It was later retracted; instead of using MDMA, methamphetamine had been used in the test.

Cardiotoxicity

Long-term heavy use of MDMA has been shown to be cardiotoxic and may lead to valvulopathy (heart valve damage) through its actions on the 5-HT2B receptor.[78][76]

In one study, 28% of long-term users (2-3 doses per week for a mean of 6 years, mean of age 24.3 years) had developed clinically evident valvular heart disease.[79]

It is strongly recommended that one use harm reduction practices when using this substance.

Dependence and abuse potential

As with other stimulants, the chronic use of MDMA can be considered moderately addictive with a high potential for abuse and is capable of causing psychological dependence among certain users. When addiction has developed, cravings and withdrawal effects may occur if one suddenly stops their usage.

Tolerance to many of the effects of MDMA develops with prolonged and repeated use. This results in users having to administer increasingly larger doses to achieve the same effects.

Upon a single administration, it takes about 1 month for the tolerance to be reduced to half and 2.5 months to be back at baseline (in the absence of further consumption).

MDMA exhibits cross-tolerance with all dopaminergic and serotonergic stimulants, meaning that after the consumption of MDMA all stimulants will have a reduced effect.

Dangerous interactions

Warning: Many psychoactive substances that are reasonably safe to use on their own can suddenly become dangerous and even life-threatening when combined with certain other substances. The following list provides some known dangerous interactions (although it is not guaranteed to include all of them).

Always conduct independent research (e.g. Google, DuckDuckGo, PubMed) to ensure that a combination of two or more substances is safe to consume. Some of the listed interactions have been sourced from TripSit.

  • SSRIs and SNRIs - may dampen the the desired psychological effects of MDMA while retaining the same level of undesirable physiological side-effects.[80][81] But unlike common belief it doesn't cause serotonin syndrome.[citation needed]
  • 25x-NBOMe - Due to the highly unpredictable and physically straining effects of 25x-NBOMe, combinations with MDMA are strongly discouraged.
  • Protease Inhibitors - Certain HIV medications like Ritonavir or Cobicistat contain protease inhibitors, that cause the liver to process MDMA slower resulting in longer and stronger effects, which causes more harm to the liver and might cause overdosing. A lower dose is recommended. [82]
  • 5-MeO-xxT - 5-MeO tryptamines are considered to be unpredictable and should be mixed with MDMA with care.
  • Alcohol - Both MDMA and alcohol cause dehydration and bodily strain. Approach this combination with caution, moderation and sufficient hydration. More than a small amount of alcohol will dull the euphoria of MDMA.
  • Cocaine - Cocaine blocks some of the desirable effects of MDMA while increasing the risk of heart attack.[citation needed]
  • DOx - The combined stimulating effects of DOx and MDMA can become overbearing, particularly during the come-up phase. Additionally, coming down on the MDMA while the DOx is still active can produce significant anxiety and bodily discomfort.
  • GHB/GBL - Large amounts of GHB/GBL may overwhelm the effects of MDMA on the comedown and place the user at risk of sudden loss of consciousness.
  • MXE - There have been reports of concerning serotonergic interactions when the two are taken at the same time, but MXE taken to the end of an MDMA experience does not appear to cause the same issues.
  • PCP - PCP with MDMA may increase the risk of excessive stimulation, mania, and psychosis.
  • Tramadol - Tramadol is well-documented to lower the seizure threshold[83] and this risk is especially elevated when tramadol is taken with MDMA.

Serotonin syndrome risk

Combinations with the following substances can lead to dangerously high serotonin levels. Serotonin syndrome requires immediate medical attention and can be fatal if left untreated.

  • MAOIs such as syrian rue, banisteriopsis caapi, phenelzine, selegiline, and moclobemide[84] - MAO-B inhibitors can increase the potency and duration of phenethylamines unpredictably. MAO-A inhibitors with MDMA will lead to hypertensive crises.
  • Serotonin releasers such as MDMA, 4-FA, methamphetamine, methylone and αMT
  • AMT
  • 2C-T-x
  • DXM
  • 5-HTP - 5-HTP is a supplement that acts as a precursor for serotonin. It is sometimes recommended to be used after MDMA experiences to try to restore depleted serotonin reserves. However, taking 5-HTP shortly before or with MDMA may cause excessive serotonin levels in the brain, which can lead to serotonin syndrome.[85] As a result, it is advised to wait until the day after the MDMA has been used before consuming 5-HTP.
